Radon

Radon is a natural radioactive noble gas that is odourless, tasteless and colourless. Radon is formed wherever its mother nuclide radium is present, for example in soil and in building materials. Radon is released into the open air and also into buildings from the subsoil. Elevated radon concentrations in indoor air may lead to health burdens. Besides smoking, inhaling radon is among the greatest risks for developing lung cancer. Small measures are often enough to significantly reduce radon levels and thereby the risk of disease.
